Great wholesale value

Bought these in bulk for a commercial shelving unit. Consistent quality across all pieces and the price point was unbeatable.

Good product, slight shipping delay

The connectors themselves are top-notch and rust-resistant. Shipping took a day longer than expected, but the product quality makes up for it.

Exactly as described

Fit my square tubes snugly. The included hardware is good quality steel, not cheap soft metal. Highly recommend for DIY structures.

Sturdy but instructions could be clearer

The build quality is excellent and feels very solid once tightened. I deducted one star because the assembly diagram was a bit small to read.

Saved me so much time

I was dreading having to weld pipes for my garden trellis. These fit the 40mm tubes perfectly and hold tight without any slipping.

Perfect for my greenhouse project

These connectors made assembling the frame incredibly easy. No welding needed, and the galvanized finish looks durable against the elements.

5 FAQ

Q: Is the galvanization thick enough for coastal areas?

A: Yes, our hot-dip galvanized coating provides high corrosion resistance suitable for harsh environments, including coastal regions with salt air.

Q: Do I need special tools to install these?

A: No special tools are required. A standard wrench or socket set is sufficient to tighten the bolts and secure the joint.

Q: Are replacement bolts available if I lose one?

A: Yes, we sell hardware kits separately. Please contact our support team with your order number to purchase individual replacement parts.

Q: Can these be used for load-bearing shelves?

A: Absolutely. Each joint is rated to support significant weight when installed correctly. Please ensure the entire frame structure is balanced.

Q: Will this fit a 35mm square tube?

A: No, this specific model is designed strictly for 30mm or 40mm square tubes. Using it with a 35mm tube may result in a loose fit and structural instability.
